Abstract:
Using a new radio sample, 6C* designed to find radio galaxies at z > 4 along with the complete 3CRR and 6CE sample we extend the radio galaxy K - z relation to z similar to 4.5. The 6C* K - z data significantly improve delineation of the K - z relation for radio galaxies at high redshift (z > 2). In a spatially flat universe with a cosmological constant (Omega(M) = 0.3 and Omega(A) = 0.7), the most luminous radio sources appear to be associated with galaxies with a luminosity distribution with a high mean (approximate to 5L*), and a low dispersion (sigma similar to 0.5 mag) which formed their stars at epochs corresponding to z greater than or similar to 2.5).UV and optical quantitative spectroscopy of early B-type supergiants in M 33
